WEBGrinding is a subset of cutting, as grinding is a true metalcutting process. Each grain of abrasive functions as a microscopic singlepoint cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

WEBJun 7, 2021 · Essentially, as a day grows humid, the effect on extraction is the same as if the grind got finer. Humidity will slow the extraction down. You have to compensate by making the grind a little coarser. Equally, on warmer days (or changes from chilly to hot days as in Spring or Summer), the espresso will tend to extract slightly faster. The effect ...
